METHOD AND DEVICE FOR RECEIVING
INFORMATION, AND COMPUTER-READABLE
MEDIUM
TECHNICAL FIELD
The embodiments of the disclosure relate to the field of wireless
communication technologies, and in particular to a method and a device for
receiving
information, and a computer readable medium.
BACKGROUND
With the development of a communication technology, the research on a 5th
Generation (5G) has been conducted. The radio access of the 5G is referred to
as New
Radio (NR). Since a frequency band adopted in the 5G NR is higher than a
frequency
band adopted in a Long Term Evolution (LTE) system, the path loss of radio
signal
transmission is increased and the coverage of a radio signal becomes small. In
a 5G
system, a beam is formed via a multi-antenna system of a base station by using
a
beamforming technology, thereby improving the gain of the radio signal and
compensating for the path loss.
In the 5G NR system, a common channel and a common signal cover the
whole cell in a multi-beam scanning manner, so that User Equipment (UE) in the
cell
can receive the common channel and the common signal. Moreover, the 5G NR
supports a wideband carrier, but due to limitation of UE capability, the UE
can
support a maximum bandwidth less than a bandwidth supported by a network
system.
Therefore, in the SG NR system, the wideband carrier of the network system is
further
configured to a plurality of Band WidthParts (BWPs).
For a paging process of the UE, under an environment of the multi-beam
scanning as well as the bandwidth of network system configured into a
plurality of
BWPs, how the UE can accurately receive a paging message is a problem that
needs
to be solved.

DETAILED DESCRIPTION
In order to be able to understand the characteristics and technical contents
of
the embodiments of the disclosure in more detail, the implementation of the
embodiments of the disclosure will be described in detail below in combination
with
accompanying drawings. The appended accompanying drawings are merely for
reference, and are not intended to limit the embodiments of the disclosure.
First embodiment
FIG. 1 illustrates a flowchart of a method for receiving information according
to an embodiment of the disclosure. The method may be applied to a UE and may
include the following operations.
At S101: association relationships between paging bandwidths and
synchronization or reference signals are acquired.
At S102: a synchronization or reference signal associated with a paging
bandwidth corresponding to the UE is acquired according to the association
.. relationships.
At S103: a paging message is received in the paging bandwidth corresponding
to the UE, according to the synchronization or reference signal.
With the technical solutions illustrated in FIG. 1, after the UE determines a
paging bandwidth corresponding to the UE, the UE acquires, based on the
acquired
association relationships between the paging bandwidths and the
synchronization or
reference signals, a synchronization or reference signal associated with the
paging
bandwidth corresponding to the UE. Thus, the UE can obtain a synchronization
and
channel state according to the synchronization or reference signal, and
receive a
paging message from the paging bandwidth corresponding to the UE. In such a
manner, the UE can receive the paging message more accurately, and the success
rate
of receiving the paging message by the UE in the paging bandwidth
corresponding to
the UE is improved.
In the embodiment of the disclosure, each association relationship can be
used for indicating that the UE receives a paging message from a paging
5
CA 03052883 2019-08-07
bandwidth. Specifically, each association relationship preferably may be a
Quasi-
Co-Location (QCL) relationship.
Moreover, in the embodiment of the disclosure, the synchronization or
reference signal may include at least one of: a Synchronization Signal block
(SS
block), a Channel State Information Reference Signal (CSI-RS), or a Tracking
Reference Signal (TRS). Specifically, the synchronization or reference signal
may
be configured by a network device to the CE. Furthermore, the SS block and the
CSI-RS are used for Radio Resource Management (RRM) and mobility
measurement, and the TRS is used for time frequency tracking.
Specifically, in a 5G NR system, an SS and a broadcast channel need to
cover the whole cell in a multi-beam scanning manner so that a CE in the cell
receives the SS and the broadcast channel. The multi-beam transmission of the
SS
is implemented by defining an SS burst set. An SS burst set includes one or
more
SS bursts, and an SS burst includes one or more SS blocks. An SS block is used
for
.. bearing an SS and a broadcast channel of a beam. As a result, an SS burst
set may
include synchronization signals of beams, of which the number is the same as
the
SS block number, in a cell. An SS block includes a Primary Synchronization
Signal
(PSS) occupying one symbol, a Secondary Synchronization Signal (SSS)
occupying one symbol and New Radio Access Technology-Physical broadcast
.. channels (NR-PBCHs) occupying two symbols. Specifically, the structural
diagram
of the SS block is illustrated in FIG. 2. In addition to the SS and the PBCH
on
which the multi-beam scanning needs to be performed, other some common
information such as Remaining Minimum System Information (RMSI) and a
paging message also needs to be sent in the multi-beam scanning manner.
For the technical solutions in FIG. 1, for the operation of acquiring the
association relationships in SI01, two exemplary implementation manners are
provided in the embodiment as follows.
In a first possible implementation manner, the operation that association
relationships between paging bandwidths and synchronization or reference
signals are
.. acquired may include the following operations.
RMSI or Other System Information (OSI) is received, where the RMSI or the
OSI is used for notifying indication information of each of the paging
bandwidths and
6
CA 03052883 2019-08-07
indication information of a synchronization or reference signal having an
association
relationship with the paging bandwidth.
It may be understood that the UE determines a paging bandwidth according to
an indication of indication information of the paging bandwidth, and acquires
the
synchronization or reference signal having the association relationship with
the
paging bandwidth according to the indication information of the
synchronization or
reference signal having the association relationship with the paging
bandwidth. In the
first possible implementation manner, for the RMSI, in the 5G NR system, a
common
search space needs to be defined for an initially accessed UE and is used for
receiving
common control information such as the RMSI. Therefore, a concept of a Control
Resource Set (CORESET) is introduced to define a resource set for carrying
control
information. The UE detects, in the resource set, a New Radio Access
Technology-
Physical Downlink Control channel (NR-PDCCH) to obtain scheduling information
of a New Radio Access Technology-Physical Downlink Shared channel (NR-PDSCH)
carrying the RMSI. Indication information of the CORESET is carried in the NR-
PBCH and is used by the UE to receive the RMSI. By the same reasoning, since
the
UE needs to receive the paging message, the UE also needs to determine CORESET
information for receiving paging indication information, i.e., CORESET for
paging.
The CORESET information is indicated to the UP via the RMSI, so that the UE
detects paging indication information according to the CORESET information to
receive the paging message.
In a second possible implementation manner, the operation that association
relationships between paging bandwidths and synchronization or reference
signals are
acquired may include the following operations.
Each association relationship is defined according to a preset association
relationship establishment strategy.
The preset association relationship establishment strategy comprises one of:
a paging message in a paging bandwidth has an association relationship with a
synchronization or reference signal on a BWP on which the paging bandwidth is
located, where the paging bandwidth is a part of the BWP and the BWP is a part
of a
system bandwidth,
7
CA 03052883 2019-08-07
a paging message in a paging bandwidth has an association relationship with a
synchronization or reference signal that is closest to the paging bandwidth in
a
frequency domain, or
a paging message in a paging bandwidth has an association relationship with a
preset synchronization or reference signal.
For the second possible implementation manner, in the 5G NR, the system
bandwidth supports a wideband carrier and the system carrier bandwidth may be
up to
400 MHz. The network device has a high processing capacity and thus can
support
the wideband carrier. However, the UE is restricted by a cost, a power and the
like
and thus the wideband supported by the HE is restricted by the capability of
the UE.
As a result, one or more BWPs are configured for a wideband carrier, and each
BWP
includes a group of continuous Physical Resource Blocks (PRBs). For a UE, in a
serving cell, it is allowed that at most one active DL BWP and at most one
active UL
BWP coexist. Moreover, before a BWP is configured for the HE, there is an
initial
active Downlink/Uplink (DLIUL) BWP. The active DL/UL BWP is within a
minimum bandwidth range of the HE so as to be received by all capable UEs.
During
a RRC connection establishment process or after the RRC connection
establishment, a
special active DL/UL BWP may be configured for the HE.
For a UE in an idle state, due to the existence of the initial active DL/UL
BWP, the most direct manner is to carry the paging message on the initial
active
DL/UL BWP to send. Since the bandwidth of the initial active DL/UL BWP meets
the
minimum bandwidth capacity of the HE, all capable UEs may receive the paging
on
the initial active DL/UL BWP. However, generally, the minimum bandwidth
capacity
of the UE is 10 MI lz, which results in that the bandwidth of the initial
active DL/UL
BWP is limited. In addition to carrying the SS block, when the paging message,
the
data and the like are to be carried simultaneously, the congestion of paging
and data
transmission on the BWP is caused and thus the paging delay is increased. In
order to
avoid such a situation, the paging messages of the UE in the cell may be
dispersed to
a plurality of different BWPs, so that the paging messages are loaded on
different
BWPs for averaging. As illustrated in FIG. 3, a paging bandwidth for carrying
the
paging message is provided on each of a plurality of BWPs of the system
bandwidth,
and different UEs each may acquire a paging bandwidth for carrying a paging
message corresponding to the HE.
8
CA 03052883 2019-08-07
In the embodiment of the disclosure, the paging bandwidth may be a
frequency domain bandwidth or a frequency domain position, which is indicated
by
the CORESET; or may also be a frequency domain bandwidth carrying at least one
of
paging indication information or a paging message. In other words, the paging
bandwidth may be a frequency domain location at which the paging indication
information and the paging message are carried, or a frequency domain location
corresponding to the CORESET for transmission of the paging indication
information, or a frequency domain location at which the paging message is
sent.
It may be understood that the paging indication information specifically may
be carried in Downlink Control Information (DCI) sent by a Physical Downlink
Control Channel (PDCCH) that is scrambled with a Paging-Radio Network Ten-Tory
Identity (P-RNTI), and the UE receives, according to the paging indication
information, the paging message carried in a Physical Downlink Shared Channel
(PDSCH).
In the system bandwidth, there may be a plurality of SS blocks, e.g., a SS
block exists in each of different BWPs, and the UE in the idle state may
detect one or
more SS blocks in the system bandwidth. When the UE determines that a paging
bandwidth corresponding to the UE has no association relationship (such as QCL
relationship) with the detected SS block(s), or that an SS detected by the UE
cannot
be used for synchronization reference when the UE receives the paging
bandwidth, it
is essential for the UE to acquire an SS or a reference signal that has an
association
relationship (such as QCL relationship) with the paging bandwidth
corresponding to
the UE. Therefore, the method illustrated in FIG. 1 may further include the
following
operation: responsive to that it is detected that the system bandwidth
includes more
than one synchronization or reference signal and the received paging bandwidth
corresponding to the UE has no the QCL, association relationship with the
detected
synchronization or reference signal, a synchronization or reference signal
having the
QCL association relationship with the paging bandwidth correspondingly
received by
the UE is acquired. Specifically, the situation in which the paging bandwidth
corresponding to the .UE has no association relationship with the detected
synchronization or reference signal may include one of:
9
CA 03052883 2019-08-07
BWP on which the paging bandwidth corresponding to the UE is located
different from a BWP on which the detected synchronization or reference signal
is
located, or
a distance between a frequency domain location of the paging bandwidth
corresponding to the UE and a frequency domain location of the detected
synchronization or reference signal is greater than a set distance threshold,
so that the
frequency domain spacing distance is larger, or
a frequency domain location of the paging bandwidth corresponding to the UE
and a frequency domain location of the detected synchronization or reference
signal
belong to different Radio-Frequency (RF) chains.
When the paging bandwidth corresponding to the UE has no QCL relationship
with the detected synchronization or reference signal, the UE needs to obtain
an
appropriate synchronization or reference signal according to the technical
solutions
illustrated in FIG. 1 for synchronization, and thus the paging message sent on
the
.. paging bandwidth is further received.
Second embodiment
Based on the same inventive concept as the foregoing embodiments, FIG. 4
illustrates a flowchart of a method for receiving information according to an
embodiment of the disclosure. The method is applied to a network device and
may
include the following operations.
At S401: indication information of a paging bandwidth corresponding to a
UE and indication information of a synchronization or reference signal having
an
association relationship with the paging bandwidth are carried in RMSI or OSI.
At S402: the RMSI or the OSI is sent to the UE.
Specifically, the association relationship includes a QCL relationship.
It may be understood that after the UE receives the RMS or the OS!, a paging
bandwidth can be determined based on the indication information of the paging
bandwidth corresponding to the UE, a synchronization or reference signal is
acquired
according to the indication information of the synchronization or reference
signal
having the association relationship with the paging bandwidth, and thereafter
a paging
message can be received according to the technical solutions in the first
embodiment,
the details are not repeated herein again.

INDUSTRIAL APPLICABILITY
17
CA 03052883 2019-08-07
In tlie embodiments of the disclosure, the UE acquires, after the UE
determines a paging bandwidth corresponding to the UE, a synchronization or
reference signal associated with the paging bandwidth corresponding to the UE
based
.. on acquired association relationships between paging bandwidths and
synchronization
or reference signals, thus the UE can obtain a synchronization and channel
state
according to the synchronization or reference signal, and receive a paging
message
from the paging bandwidth corresponding to the UE. In such a manner, the UE
can
receive the paging message more accurately, and the success rate of receiving
the
paging message by the UE from the paging bandwidth corresponding to the UE is
improved.
